Ovulation could occur early or late and not hit exactly in the middle of the cycle. If you have a 30-day cycle, that means you are likely to get pregnant 15 days after the start of your menstrual period, which also is 15 days before the start of your next period. So, yes, you can get pregnant before and after your period.
This means that this gal can get pregnant by having unprotected sex starting 7 days before ovulation date (or on the 7th day after menstruation started, in this case it's the same), and about a day after. Just so we're clear, this means from day 7 to day 15. We have no clue as to how long your cycle is.
